Most people have probably thought at one time or another, why isn't 4/4 time the same as say 8/8 time or 2/2 time? (Anyone who knows about reducing fractions can attest to that).
I think time signatures really are anachronistic. Really you just want to know is there 3 beats, 4 beats or even 5 beats in a bar.
Mostly the only ones used are 3/4, 4/4 and very rarely 5/4.
So is it just convention to use this method. Or is there some hidden meaning. I mean a semibreve is always 4 crotchets no matter what the time signature is.
So is this just an anachronism we have to put up with or does anyone find this weird way of expressing the beats in a bar useful?
